NSULATING JACKET OR COVERING.

SPECIFICATION forming part of Letters Patent No. 396,933, dated January 29, 1889.

Application tiled February 27, i883. Serial No. 265,381. (No model.)

To all zrtom 'it may concern:

'Be it known that l, WILLIAM J. HULEOED, of Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Insulating' .lackets or Coverings, oli which the following,I is a description sufficiently full, clear, and exact to enable any person. skilled in the art or science to which said invention appertains to Io make and use thc same, reference beine' had to the accompanying` drawings, Yforming' part ot' this specification, in whichlfigu re l. is a side elevation oit' a dinner-pail. provided with my improved jacket or covering; Fig. 2, a like view showingl certain modiied details ot' construction, and Fig. an enlarged vertical transverse section of a piece ot the jacket.

Like letters and figures ol reference indi- :zo cate correspoiulinel parts in the different fig'- ures of the drawings. l

My invention relates to that class of jackets or coverings which are designed for keepingl the contents ol' dinner or lunch pails 2 5 warm by preventing' the radiation of heat; and it consists in certain novel features, as hereinafter .fully set forth and claimed, the object being to produce a simpler, cheaper, and more eitective article et this character 3o than is now in ordiilary use.

The nature and (meration ot' the inn'novement will be readily understood by all conversant with such matters from the following` explanation.

In the drawings, A represents the body of the pail, B the cover, and C the bail, the body and cover being; shown by dotted lines.

' In the present instance a round or cylindrical pail is represented; but a pail olf any 4o suitable form, size, or construction may be used. The body D oit' the jacket is of suitable size and shape to iit the body A of the pail, over which it is drawn in use. The cover E of the jacket .is also of suitable size and t'orm to fit the cover B et' the pail, and is provided with a dowiiwardly-pioi ectin annular tl ange, t, which passes down over the top oi' the body D when in position i'or use. Side slots or recesses, ar, are formed .in the fianget for the rcception of the bail C, and there is also an open- 5o ing,` in the top et' the cover E for the reception ot' the knob 7;. ot the cover B. Attached to the body D oli the jacket there are elastic straps II, (see Fig'. l,) provided at their upper ends with triangular loops d. Attached to the corner of each of the Flaps u of the cover E, formed by the slots 1r, there is a hook, 5, adaptedv to engage the loops (l.

In securing the cover E in position on the body D the loop (l at each side of the pail is 6o passed over the hooks .2', and as the elastic straps II contract the cover will not only be drawn downward tightly onto said body, but the flaps zr will be drawn toward each other by the action of the inclined sides a of the loops (l on the hooks z, thereby causingl the lower portion of the Iiange t to hug' the body D closely and the heat to be retained more perfectly than would be the case it' the cover were merely forced downward without havin g 7o the flaps 'zr drawn together.

Instead ot' usin elastic straps II, inelastic straps may be employed, said straps being divided and provided with buckles to exert a strain on the loops d, if preferred. An eye in which the loop d is inserted may also be employed instead of one of the hooks .2f when a buckle is used in the strap II, if desired.

I sometimes provide the body D, as shown in Fig. 2, with vertical loops g, and the iiaps 8o U with straps 71. and buckles o', said straps bein in sertcd in. said loops and the 'iiaps drawn together and secured by the straps and buckles, the loops and straps also serving' to attach the cover E and body D to eachother.

The outer portion ot' the jacket is composed of rubber cloth or similar water-prooi' material, lz", which is lined with lflannel, felt, or similar non-conductingl material, zu.

It is well known that in transporting pails 9o of this character they are frequently exposed to rain, which evaporates on striking' them, and thereby rapidly cools their contents. The water-prmrl material 1T is designed to obviate this, and fully accomplislles the purpose for 95 which it .is employed.

In the drawings but one side ot the pail is shown and one set of fasteners for attachingthe cover of the jacket to its body; but it will be understood that the jacket is provided with a corresponding set of fasteners at the opposite side of the'pail, and that the cover E has two slots, standing opposite each other.

Having thus explained my invention, what I claim isl. In a jacket or covering of the character described, the insulating-cover E, having the flaps 'o r, provided with the hooks 5, in coinbination with the insulating-body A7 provided with the loops d, and means, substan-V tially as described, for exerting a strain on said loops when engaged with said hooks, substantially as set forth.

2. The insulating-body A, having the elastic straps H, provided with triangular loops d, in combination With the insulating-cover E, having the side slots or recesses, forming flaps n, said cover being provided with hooks 2, substantially as described.

3. In a jacket of the character described, the insulating-cover E, having side slots or recesses forming flaps fr, said 'aps being provided with hooks, in combination with the insulating-body A, provided with a loop for receiving said hooks, whereby the flaps maybe drawn together, substantially as described.
